(And yes, I know that we already had satellites by 1961. But not powered by TDs)Hello, Tom and the group--
I dimly recall a mention of 100-ampere tunnel diodes, likely lab curiosities

application might have served as switches in a DC-to-DC convertor fed
by power from low-voltage sources (thermopiles?).
